Central Parkway was the main routes through the west side of Cincinnati, Ohio. Outside of downtown Cincinnati, this is the part of the city that I was most familiar with because my father's employer, The American Can Co. was located in this neighbor hood until 1962. The first major landmark that one would pass was Union Terminal.
Even at 1/64th scale, Union Terminal takes up quite a bit of real estate and this model excludes the parkway approach to the terminal.
